just learning how to use a new to me 550b. The thing that I am most struggling with is using the primer pickup tube. I will get about 4 or 5 and they want to turn sideways, just as they ar going from the tip into the tube. I have had a few that filpped around and ended up in the magazine backward. This is happening with small primers using the yellow tip. I have a fresh yellow tip in my spare parts bag, and tired to but am having the same issue, When watching videos, it looks to be as easy as falling down but it is really frustrating me. What am I doing wrong?
